Printing hanging tests
Hanging test : org.apache.hadoop.hbase.util.TestBytes

There is this in the output:
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-surefire-plugin:2.18:test (default-test) on
project hbase-common: ExecutionException: java.lang.RuntimeException: The
forked VM terminated without properly saying goodbye. VM crash or System.exit
called?
We were killed.
My changes to test-patch.sh are only going up this evening. Main change was
removing killing of 'found' processes. Hopefully this is cause of such as the
above. I'm a bit disturbed by your reports that you are starting to see
hbase-server timeout... let me try over here on my little rig again....

> Patch build are now failing most of the time because we are dropping zombies.
> I confirm we are doing this on non-apache build boxes too.
> Left-over zombies consume resources on build boxes (OOME cannot create native
> threads). Having to do multiple test runs in the hope that we can get a
> non-zombie-making build or making (arbitrary) rulings that the zombies are
> 'not related' is a productivity sink. And so on...
> This is an umbrella issue for a zombie stomping session that started earlier
> this week. Will hang sub-issues of this one. Am running builds back-to-back
> on little cluster to turn out the monsters.
